FPGA cards?

[royce]

I don't think there is much practically possible yet. The hashcat framework is now there to be developed against, but it is subject to both hardware capabilities and an actual OpenCL implementation on that FPGA. As I understand it, OpenCL support for most FPGAs is spotty or nonexistent (but that's only based on a little bit of research, so YMMV).

The only practical publicly available FPGA cracking that I know of is John the Ripper's recent support for descrypt on the ZTEX 1.15y quad boards. And it is not OpenCL-based.
